BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a transportation system. More specifically, the present invention relates to a transportation system with integrated infrastructure and multi-modal transport vehicles.

2. Description of the Background Art

Most everyone is familiar with transportation infrastructure such as the highways, streets, roads and limited access Interstates that cars travel upon. Although widely used, such infrastructure has many shortcomings. Vehicles traveling on conventional highways require the continuous attention and skill of the vehicle operator. These skills, however, can vary based on experience, age, health, mental condition, disposition, medication, drug influences, alertness, and distractions. Moreover, anyone lacking the requisite skill and/or attention can suffer dire and fatal consequences. Tens of thousands of individuals lose their lives in vehicle crashes each year.

Conventional highways are also vulnerable to weather conditions such as ice, rain, snow, grease, hydroplaning, silt, mud, strong winds, lightning, fog, and smog visibility which affects both vehicle control and traction. Night conditions, visibility and lightning can add to the difficulty of the driver.

Conventional highways are also required to be much wider than the vehicle because even skilled drivers cannot steer the vehicle along a precise path. Broad shoulders are also required because vehicles occasionally run off the road, need recovery space, and sometimes require emergency parking.

Vehicles traveling upon conventional highways are also prone to accidents that result in the vehicle running off of the highway, hitting stationary objects, rolling over, going into water, or traveling down embankments. Vehicles can likewise be involved in collisions with other vehicles. Furthermore, because highways are typically built on the surface or on grade, both the highway and the vehicles traveling thereon present a hazard to children, pedestrians, pets, wildlife, and bicycles.

Highways are also undesirable because they require a broad finished asphalt or concrete surface even though the wheels of vehicles actually use only a fraction of this surface. This creates a large heat sink and results in undesirable water run off.

Conventional highways are also used as a passage way for a variety of municipal services, such as sewer lines, telephone lines, and power lines. The areas above and below our highways are often crowded. When services go into the ground they become less accessible, harder to find, create interference with one another and are subject to more corrosive forces. When services go overhead they create clutter and the wooden or concrete supporting poles are a hazard.

There is also the disadvantage that with all the problems of vehicle control, potential mechanical failures, highway conditions and the limitations of human operators the vehicles cannot safely travel at speeds up to the aerodynamic and physical potential of the vehicle.

It is an objective of the present invention to overcome these deficiencies by providing a transportation system with an integrated infrastructure and by further providing multimodal vehicles.

SUMMARY OF THE INVENTION

One of the advantages of the present system is achieved by providing a transportation system with an integrated infrastructure.

Yet another advantage is realized by providing a transportation system with multimodal vehicles.

Still yet a further advantage is realized by creating a rail structure wherein the contact surface for wheeled vehicles is minimized.

Another advantage results in a transportation structure that permits vehicles to travel on a contact surface or on rails.

The system also realizes advantages by providing a guideway structure that can carry associated municipal equipment such as power lines, telephone lines, and/or sewer lines.

These and other advantages are accomplished by providing a transportation system with integrated infrastructure. In one embodiment, this infrastructure takes the form of a hollow elevated load bearing guideway structure designed to support the weight of traveling vehicles. The structure supports a backbone beam, or rail, that has multiple functions. These functions may include vehicle control, security, and energy delivery. The structure is bimodal meaning vehicles can have wheels like cars or steel rimmed wheels like a train or any combination thereof. The hollow guideway structure can contain a variety of utilities. The guideway structure can be supported on a hollow tower that includes a conduit and an access corridor for all associated utilities. The system also includes vehicles with bimodal wheels which enable the vehicle to travel on rails on the guideway or on a contact surface on the guideway. Additionally, the vehicle can travel on conventional roads. The bimodal wheels are such that the vehicles using them can travel effortlessly from a flat paved surface onto the rails of the guideway without concern for misalignment. By combining a paved contact surface for wheeled vehicles and rails for steel rimmed vehicles the integrated infrastructure of the present invention blends some of the best attributes of both systems into a seamless and truly integrated bimodal transportation system.

The foregoing has outlined rather broadly the more pertinent and important features of the present invention in order that the detailed description of the invention that follows may be better understood so that the present contribution to the art can be more fully appreciated. Additional features of the invention will be described hereinafter which form the subject of the claims of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention relates to a transportation system with integrated infrastructure. In one embodiment, this infrastructure takes the form of a hollow elevated load bearing guideway structure designed to support the weight of traveling vehicles. The structure supports a backbone beam, or rail, that has multiple functions. These functions may include vehicle control, security, and energy delivery. The structure is bimodal meaning vehicles can have wheels like cars or steel rimmed wheels like a train or any combination thereof. The various components of the present invention, and the manner in which they interrelate, are described in greater detail hereinafter.

Elevated Guideway

FIG. 1 shows the preferred embodiment of the transportation system 20 featuring an elevated guideway 22. FIG. 2 is a detailed end view of the guideway structure 24 upon which the vehicle 26 travels. In a preferred but non-limiting embodiment, guideway structure 24 is in the form of a triangle approximately six feet long on each side. There are three structural triangle shaped beams. These include two upper triangle beams 28 in each corner and a lower triangle beam 30. This configuration maximizes the strength to weight ratio. Each structural triangular beam has a solid triangular stiffener to add further strength. This includes stiffeners 32 for the upper triangle beams 28 and a stiffener 34 for the lower triangle beam 30.

The two upper triangle beams 28 are joined by a cross beam 36. An additional cross beam 38 rests on top of lower triangle beam 28 to distribute the load from tubular struts 42. Tubular struts 42 serve to join triangular beams 28 and 30. A vertical strut 44 is preferably included for joining horizontal beam 36 to cross beam 38. Components 36, 38, 42, and 44 are in a plane. Components 42 and 44 transfer the load from beams 26 and 36 to lower triangular beam 30. Center strut 44 also provides vertical support for the bottom of backbone beam 46.

As noted in FIGS. 7 and 8, cross bracing stiffeners 48 and 52 are included to prevent racking and twisting of the frame. A skin sheathing 54 may be added to the sides of the guideway structure 24 to add aesthetics and further strength. It is understood further structural analysis may modify or add bracing.

FIG. 3 is a detailed view of one of the upper triangular beams 28 taken from FIG. 2. This view shows details regarding the surface of beam 28. A contact surface 56 rests on beam 28 and supports a contact surface tread 58 and a structural rail 62. Contact surface tread 58 is filled with a high strength epoxy based filler, a unidirectional reinforcing carbon fabric 64 and a hard durable finish surface 66. This is the contact surface the vehicle wheels will travel on. When the contact surface is worn and needs replacement or refinishing the contact surface tread 58 is removed and shipped back to the factory.

By way of this construction, instead of thousands of tons of petroleum based asphalt to grind up and replace there will be a surface only a few inches wide and about two inches thick. FIGS. 4-5 show how the ends of the contact surface treads 58 will be finished in order to allow for expansion and to minimize road noise. Looking at the top view there is a small opening 68 cut at a sharp angle. Looking at the side view the thickness of the material is sliced back at an angle so that the vehicle wheels do not cross the expansion joint all at one time. This will prevent the familiar clickety clack of concrete paved roads.

The structural rail 62 is capped with a contact crown rail 72. Vehicles using bimodal wheels with steel rims will ride on the contact crown rail 72. Contact crown rail 72 is made to be easily and inexpensively replaceable when contact wear causes damage to its surface. A clamp 74 on the underside of beam 28 slides over a trough on each side of contact surface 56 to lock it in place.

Backbone Beam

The backbone beam 46 is a component of the guideway 22 and has several purposes. Backbone beam 46 is shown as an I-beam rail; however, it is understood this backbone beam could have numerous other configurations such as a T, U, C, E, V, W, etc. rotated in various positions. Any such shapes are acceptable provided they enable the backbone beam to accomplish its purposes. A primary purpose of backbone beam 46 is to serve as a source of reference for vehicle mounted sensors that provide guidance to vehicles 26 upon the guideway 22. A suitable sensor arrangement is described in co-pending application Ser. No. 61/221,701 (hereinafter '701 application) filed on Jun. 30, 2009 and entitled “Sensory Stabilizer Saddle.” The contents of this co-pending application are fully incorporated herein. Another purpose is to provide secure vehicle stability for occasions when road conditions or weather is hazardous.

Backbone beam 46 also prevents hijacking of vehicle 26 and likewise provides emergency steering control in the event of electronic systems failure. Backbone beam 46 assures all vehicles 26 remain on the guideway 22 at all times. Backbone beam 46 serves as a mechanism for delivering electricity to some or all vehicles on the guideway 22. Furthermore, backbone beam 46 is a passive component in the guideway switching process whereby a vehicle can switched off of one guideway onto another. This switching process is likewise described in the '701 application.

Backbone beam 46 provides an immovable surface for emergency braking of vehicles 26 and allows guideway 22 to use the contact surface treads 58 because it provides precise and predictable tracking of vehicle wheels. As such, backbone beam 46 provides both positive tracking and fail safe control and permits use of the guideway 22 in all weather conditions. The associated traction control ensures that vehicles 26 cannot be blown off or torn apart in a hurricane, tornado, or earthquake. Likewise, vehicles cannot slide off or roll off due to snow, ice, mud, rain, wind, or grease. Fail safe control means positive control in the event electromagnetic wave, electric, smog, fire, smoke, rain, mist or any electric disturbance disrupts wireless communication. The traction control and fail safe aspects of the invention are more fully described in the '701 application.

FIG. 6 illustrates a section of backbone beam 46. In addition to the functions described above, backbone beam 46 is also used in delivering electricity to vehicles 26 riding upon beam 46. In the preferred embodiment, power is transferred from an electrical supply assembly 76 to a corresponding saddle 78 on the underside of vehicle 26 (note FIG. 1). Saddle 78 and supply assembly 76 close an electrical circuit to power vehicle 26. Electrical supply assembly 76 preferably includes a electromagnetic radiation shield 82, a dielectic electrical insulator 84 and a conductive electric surface 86. Electric surface 86 provides an electrical conductor to supply electricity to a corresponding electrode in saddle 78. Here the backbone beam 46 provides both support for the conductor assembly and it provides protection of the conducting surface from weather conditions. The electrical supply assembly 82, 84, and 86 may be continuous along the length of the guideway or it may be a segment used for pulse charging as vehicles travel by. Vehicles 26 on the guideway will not have to be electric. They may use batteries, fuel cells, capacitors or any suitable source of energy.

Guideway 22 will ideally be able to provide electric power to battery powered, capacitor powered, or any electrically powered vehicle when vehicles enter the guideway 22. The power should be sufficient for vehicles to quickly accelerate up to full speed along guideway 22. In addition, guideway 22 may also supply electric power to standing or parked vehicles so any electric energy storage devices on board the vehicle may be charged.

FIG. 1 shows the guideway structure 24 supported by a hollow structural support column 88. The support column 88 is preferably a hollow reinforced concrete elliptical shaped tower that supports guideway 24 and provides a channel for integrated infrastructure to travel to and from guideway 24. Column 88, in turn, connects to one or more base openings 92, which can be a type of manhole structure that provides a base to support column 88. Base 92 provides access for utility workers to install integrated infrastructure. Bases 92 also interconnect with one or more large diameter underground conduits 94. Conducts 94 may house sewer mains, water mains, broadband fiber and/or electrical distribution. These lines, in turn, can be connected to the hollow portion of guideway 24 via a base 92 and column 88.

FIG. 1 also illustrates a shield 96 that can be installed on either side of guideway 24. In the preferred embodiment, shield 96 is a non-structural environmental shield (NSES). Such a shield obstructs visual observation of vehicles from the view of observers on the ground. It also diverts the sound of high speed vehicles so they are not heard on the ground. The shield also provides a feeling of security to any passengers on the guideway who are bothered by height. The shield is also used to make the guideway more attractive and protect pedestrians below the guideway from rain. It can be used to support LED area lighting 98 for any roadways or sidewalks below the guideway. Thin film photovoltaic solar energy collectors may be installed on the upper surface of shields 96. These may be particularly beneficial on guideways that travel east to west as they would have sun exposure for longer periods.

FIG. 1 further illustrates some of the utilities infrastructure associated with guideway 24. Integrating utilities infrastructure with guideway 24 would reduce clutter associated with numerous overhead cables. The integrated utilities infrastructure may include high voltage transmission lines. Electrified guideway 24 may also need a high voltage supply direct from the power grid. If guideway 24 provides pulse charging to vehicles 26 it will need super cooled devices for providing that service. Any high voltage transmission lines may be constructed from superconductor cables. Super conductor cables are brittle ceramic so they can not be strung on outside power poles. The guideway structure 24 provides a rigid structure that protects the conductors and components from lightning, wind forces, ice loads, and provides easy access. Therefore, guideway 24 can be used for transmitting electric, for local distribution, to provide electric for automotive traffic signals, and LED lighting for the roadway below. All power poles can be eliminated so there is room for the guideway.

Guideway 24 can be installed in high density or otherwise intensely developed metropolitan areas. Using guideway 24 as a conduit for utilities infrastructure would solve problems associated with crowding in such areas. Several possible utilities are shown. Possible lines to be routed through guideway 24 include, inter alia, super cooled high voltage transmission lines 102, lower voltage electric distribution lines 104, fiber optic cables 106, fiber optic cable for proprietary broadband 108, and other miscellaneous communication cables 112. Fresh water and sanitary sewer force mains (114 and 116) can likewise be included. All such lines can be routed from the interior of guideway 24, through column 88, base 92 and conduit 94.

Vehicle and Bimodal Wheels

In the preferred embodiment, system 20 utilizes vehicles 26 using bimodal wheels 120. FIGS. 10-17 illustrate a variety of bimodal wheel configurations. However, FIG. 12 illustrates the preferred bimodal wheel configuration. Any of the bimodal wheels of FIGS. 10-17 are designed to operate on disclosed guideway structure 24. In each instance, the entire weight of vehicle 26 is supported by the wheels 120 on the contact surface 56. Additionally, vehicle steering is provided by sensory steering referenced off of the backbone beam 46. Such sensory steering is described in the '701 application. Alternatively, steering can be accomplished by rails on the sides of guideway 24. Vehicles 26 with bimodal wheels 120 can also operate on guideway 24 with the entire weight of vehicle 26 being supported by rails 62. In this case, steering of the vehicle would also be provided by the rails. Vehicle 26 employing bimodal wheels 120 can get off guideway 24 and travel on conventional road surfaces.

In FIG. 14, wheel 120 is the regular vehicle wheel with diameter 122 that travels on the contact surface of the guideway. The outside face of the wheel is protected with a steel bumper rim 124 with diameter 126. When the guideway 24 has rails 62 the steel bumper rim 124 may rub against the steel rails 62. The outside diameter 128 of the steel bumper rim 124 has a taper 132 that prevents wheel 120 from climbing onto steel rail 62. The radius of the wheel 120 less the radius of the tapered rim 124 must be less than the height of the lowest steel rail 62 so wheel 120 slides past rail 62. However, the radius of wheel 120 less the radius of the steel bumper rim 124 before it tapers must also be less than the height of the lowest rail 62. The taper 132 of steel bumper is the steering edge but the rim 124 is the buffer surface. This is illustrated in FIGS. 16-17, where the steel buffer rim 124 and tapered flange 132 are brushing against the rail 62.

FIG. 13 illustrates another embodiment of a bimodal wheel 120. It has a regular wheel surface 134 that operates on a flat roadway surface. It also includes a steel wheel rim 124 that rides on the top of the contact rail 62. A space 136 separates the regular wheel 134 from the steel wheel rim 124. Wheel rim 124 rubs up against the side of the contact rail 62 and provides directional control to vehicle 26 and also protects the regular wheel 134. A flange 138 is also included to enable a vehicle 26 with bimodal wheels 120 to come off of a conventional flat surface roadway and drive onto an access ramp and allow vehicle 26 to seamlessly drive right up on rail 62.

In FIG. 13 the distance 142 is the difference in the radius between the wheel 134 and the steel rim 124. This distance 142 is less than the height of a standard rail but greater than the height of a short rail. The distance 144 is the difference in the radius between the wheel 134 and the leading edge diameter of the self mounting flange 138. This distance 144 is greater than the height of a standard rail. The distance 146 which is the difference between 144 minus 142. This differential enables bimodal wheel 120 to automatically ride up on the standard rail 62.

This self mounting aspect of the bimodal wheel 120 is illustrated in FIGS. 16 and 17. Here, the self mounting rail rim 138 is seen approaching above the standard rail 62. As the bimodal wheel moves closer to the rail the self mounting rail rim 138 will come into contact with the tapered surface 132 and the steel rim 124 will slide onto the rail as shown in FIG. 17. In FIG. 17, the height of rail 62 is greater than the distance between the outside of wheel surface 134 and flange surface 138, so the wheel is left up in the air by a distance (t).

FIG. 12 illustrates another embodiment of the bimodal wheel 120. In this embodiment, the steel wheel rim 124 is replaced by a concave groove 148. Other groove arrangements, such as a v-groove, or other shaped grove, can also be employed. As illustrated, groove 148 fits onto rail 62. In this regard, the top of rail 62 can be made to specifically fit into groove 148.

Furthermore, the steel wheel rim 124 does not have to be at the front or back surface of wheel 120. Rim 124 can be anywhere along the thickness or depth of the tire. The location depends upon the guideway design and upon where the rails are located along the contact surface of the infrastructure.

As shown in FIG. 12, the bimodal wheel 120 can have an additional all terrain or all purpose off road wheel 152 with a diameter 154 larger than the diameter 122 of the regular wheel 134. When vehicle 26 is on guideway 24, if the depth of the rim 156 is less than the height of the rail 62 then the vehicle weight will be riding on the rail 62 and will be steered by the rails 62. If the depth of the rim 156 is greater than the height of the rail 62 then the weight of the vehicle will be supported by the wheel 134 on the contact surface 56 and the vehicle will be steered by the rail 62. When the vehicle leaves the guideway 24 the weight of the vehicle 26 will be on the all-purpose tire 152 and the vehicle will be steered manually. This embodiment illustrates the flexibility of the bimodal wheel a vehicle equipped with bimodal wheels can not only operate on rails, on the guideway contact surfaces, or paved asphalt roads, but it can also be an all-terrain vehicle that can travel on dirt, gravel, grass, sand, muddy mountain trails, or on a beach.

Another advantage to bimodal wheels is realized when using the wheels 120 on especially large or heavy vehicles. When conventional trains operate in areas where the railroad bed has to climb steep grades they have a big problem. Iron wheels on iron rails have little traction. In order to improve traction they carry sand and the sand is applied in front of the wheels as they climb steep grades. In addition they may have additional engines on that section of a rail road to help pull the load up a grade. Even then trains are limited to mild uphill grades compared to automotive vehicles.

With the disclosed guideway 24, very large vehicles may be operate on standard rails 62. However, when vehicle 26 claims steep grades, rails 62 will be shorter such that the weight of the vehicle is supported on wheels 120 upon contact surface 56. Contact surface could be modified into a gritty surface that can provide more traction to the wheels 120 than the vehicles would otherwise have on rails 62. This gives vehicle 26 greater traction using its wheels 120 rather than rails 62. In such an embodiment, vehicle 26 is still steered by rails 62, but the weight is on contact surface 56. The ability to climb steeper grades is important. It means that routes through mountains can be selected that will be much shorter. It also means that on a per foot or per mile basis, the cost of constructing the roadway will be reduced substantially. In the long run the shorter roadway through mountains means large numbers of vehicles will get through faster and will expend less energy. So, this becomes a continuous operating benefit and savings.

FIG. 10 shows a modified bimodal wheel 120 that would be located on carriages located midway on vehicles 26 to address issues related to sliding. Sliding may occur, for example, if the wheels are located on articulated carriages. These articulated carriages would permit vehicle 26 to round turns on the guideway structure 24. It has been discovered that articulated carriages along the middle part of vehicle 26 are susceptible to sliding. To counteract this, steel rim 158 is made several times wider than the steel rail so as the rail 62 moves side to side the rail is still under the tire. This modification works on curves that are not real sharp.

FIG. 11 is another embodiment of a bimodal wheel 120 that addresses issues related to sliding. The steel rim 158 now constitutes the entire wheel 120, and the diameter 162 of the wheel 120 is the diameter of the steel rim 158. It has self tracking tapered rims 164 with a diameter 166. Steel rim 158 allows tires 120 on the mid length located carriages to follow the rails even as the tires 120 are otherwise shifting from side to side. These intermediate wheels provide traction to push the vehicle forward (and can provide regenerative braking) and they support their share of the load, but they do not provide steering. Instead, steering is accomplished via the wheels of the front and back carriages. If the rails are turning so sharply that the wheels in FIGS. 10-11 are not wide enough the wheels may lose contact with the rails and may be supporting no load and providing no traction. This will shift the load and traction to the wheels that are in contact. The self tracking tapered ends 164 of the wheels will bring them back on the tracks when they come back into alignment.

The contact surface of these bearing and traction wheels do not have to be steel. The surface can be more suitable for greater traction and for use on the contact surface or for use on a paved road. If the vehicle gets off the guideway then these wheels can drop down and come in full contact with a paved surface.

These wheels are wide and may support a different kind of motor. These wheels may house motors with greater torque but perhaps lesser efficiency. These motors may operate when the vehicle is accelerating and so needs lots of torque, or when it is braking and needs lots of regenerative braking. When the vehicle is operating on a relatively flat surface at a constant speed these mid vehicle in wheel motors may shut off and the vehicle would use only the more efficient in wheel motors in the front and rear carriages. Then all these bearing wheels would be doing is helping to carry the load.

Access Ramp

FIG. 18 shows a top view of a generalized guideway infrastructure access ramp. The access ramp is for vehicles with any of the wheels discussed above used on bimodal vehicles of any kind described herein. The flat paved access ramp begins at 168 with edges of pavement 172. As vehicle 26 moves forward in direction 174 it is under manual control. The driver of vehicle 26 must maneuver the vehicle onto the guideway. The guideway ramp makes this process simple. The side rails 176 are short rails. The driver is to line the vehicle up with the center stripe 178; however, if the vehicle meets the short rails it will be funneled in until at location 182 the saddle shoe 78 that all of the vehicles must have enters the chute 184. The dimensions of 182 and 184 and vehicle 26 are such that the saddle 78 can only go into chute 184. At location 188 the saddle chute 184 is only a couple inches wider than the saddle 78 and saddle 78 is guided onto the vertical backbone beam 46 at 192 that flares out at position 194. If the vehicle is bimodal for rails then wheels on both sides of the vehicles will be on the rails at location 188 however, these are short rails 176. The rails are not supporting the vehicle weight, but they are steering the vehicle. At location 196 the short rails become standard rails 62 which get taller and then support the weight of the vehicle. This completes the description of how vehicles use the passive access ramp to get onto the integrated multimodal guideway.
